ENZYME entry: EC 3.2.1.192

Accepted Name
ginsenoside Rb1 beta-glucosidase
Reaction catalysed
(20S)-ginsenoside Rb1 + 2 H2O <=> (20S)-ginsenoside Rg3 + 2 D-glucose
Comment(s)
  • Ginsenosidases catalyze the hydrolysis of glycosyl moieties attached to the C-3, C-6 or C-20 position of ginsenosides.
  • They are specific with respect to the nature of the glycosidic linkage, the position and the order in which the linkages are cleaved.
  • Ginsenoside Rb1 beta-glucosidase specifically and sequentially hydrolyzes the 20-[beta-D-glucopyranosyl-(1->6)-beta-D glucopyranosyloxy] residues attached to position 20 by first hydrolyzing the (1->6)-glucosidic bond to generate ginsenoside Rd as an intermediate, followed by hydrolysis of the remaining 20-O-beta-D- glucosidic bond.
